- FIG. 7 is an exploded perspective view of the optical module of FIG. 1 wherein the left half of the fastening structure is removed.
- an optical module 100 includes an optical transceiver 1 , a fastening structure 2 and a dust cover 3 .
- the optical transceiver 1 is of a BOSA module
- the dust cover 3 is located at a front opening 216 of the fastening structure 2 for preventing dust contamination from the chip inside the optical transceiver 1 .
- the fastening structure 2 and the dust cover 3 are both made of plastic.
- the optical transceiver 1 includes a body 11 , a plurality of first connecting legs 12 along the first direction, a plurality of second connecting legs 13 initially extending along the second direction perpendicular to the first direction, and successively along the first direction.

- the fastening structure 2 includes a plurality of through holes 20 through which the first connecting legs 12 and the second connecting legs 13 extend.
- the first connecting legs 12 and the second connecting legs 13 are mounted to the corresponding through holes of an external printed circuit board (not shown) on which the optical module 100 is mounted.
- the through holes 20 are used to assure true positions of the first connecting legs 12 and those of the second connecting legs 13 for facilitating mounting the optical module 100 upon the printed circuit board.
- the fastening structure 2 includes a left/first half 21 and a right/second half 22 commonly forming a receiving cavity 23 with a front opening 216 , wherein the body 11 of the optical transceiver 1 is received in the receiving cavity 23 .
- the left half 21 and the right half 22 are respectively equipped with the mounting posts 24 for mounting to the printed circuit board.
- the left half 21 includes a bottom wall 211 with a plurality of through holes 20 formed therein, the left side wall 212 and the front wall 213 .
- the plurality of through holes 20 include the first through holes 201 for extension of the first connecting legs 12 , and the second through holes 202 for extension of the second connecting legs 13 , wherein the first through holes 201 are closer to the front wall 213 than the second through holes 202 are.
- the bottom wall 211 includes a platform 214 and a recess 215 wherein the first through holes 201 is formed under the recess 215 .
- the front opening 216 extends through the front wall 213 to have the receiving cavity 23 communicate with the exterior.
- the left side wall 212 includes a left front side wall 2121 close to the front wall 211 , and a left rear side wall 2122 behind the left front side wall 2121 .
- the left rear side wall 2122 protrudes further toward the receiving cavity 23 , compared with the left front side wall 2121 .
- a guiding slot 2123 is formed in the left front side wall 2121 along the front-to-back direction.
- the right half 22 includes a bottom wall 221 , a top wall 222 , a right side wall 223 and a plurality of divider 224 extending from an interior surface of the right side wall 223 toward the left side wall 212 wherein the second connecting legs 13 are retained in the retaining groove 225 between the dividers 224 .
